Adaptive joint power and bandwidth allocation for CoMP

Abstract

It studies how to implement power allocation and bandwidth at the same time in coordinated multi-point transmission. Existing research is unrealistic to assume that the state of the wireless channel and the number of active users have not changed during a certain period of time. Since the number of active users connected to the base station and the wireless radio channel quality change over time, the existing power and bandwidth allocation scheme is no longer optimal, the optimum solution changes according to the changing network state. Also, the iterative resource allocation result value converges within an earlier time. Therefore, in this paper, we propose a new algorithm that can adapt to changing network conditions and improve convergence speed. Also designed to be compatible with distributed systems. Experimental results show that the proposed algorithm can allocate resources faster than conventional algorithms, shorten user's data transfer time, and improve system throughput
